There is a need for more accurate prediction in surgical orthodontic treatment. Video imaging is an important technology in planning orthognathic surgery and educating patients about the esthetic results after treatment. Preoperative and postoperative lateral cephalogram of 30 patients who had one piece Le Fort I osteotomy advancement and mandibular set back by bilateral intraoral vertical ramal osteotomy with or without genioplasty were used in this study. The computer generated soft tissue line drawing prediction were compared with the actual postoperative cephalograms .The results are as follows. 1. 14 variables showed Statistically significant differences from 24 variables between computer predicted profile and post operative profile 2. Most of the differences were found in the maxilla-related soft tissue landmarks. 3. The predicted results were more accurate in the groups who had small amount of mandibular set back. 4. The predicted results were more accurate in the groups who had no genioplasty. Most of these differences were within 2mm ranges. Therefore profile change prediction by video imaging could be considered clinically acceptable.

Objectives: To investigate the neurophysiological effect of acupuncture treatment on insomnia patients using quantitative electroencephalography (QEEG) and standardized Low Resolution Brain Electromagnetic Tomography method (sLORETA).Background: Insomnia is one of the commonly encountered symptoms in primary medical care. Recent studies of acupuncture for insomnia reported that the acupuncture groups showed significant improvements compared with the control groups. However, the neurophysiological mechanism of acupuncture in the treatment of insomnia has not been revealed and a few studies have measured the effect of acupuncture treatment using QEEG.Methods: Participants who had some problems in initiating or maintaining sleep, or had non-restorative sleep for more than 3 days a week and ISI scores above 8 and below 21 were treated by acupuncture for 2 weeks (3 times a week, total 6 times). We assessed the effectiveness of acupuncture for insomnia by the PSQI (Pittsburgh Sleep Quality Index) at baseline and at 2 weeks after the end of treatment (4th week). Also, we performed EEG and analysed the EEG data at baseline and at the end of treatment (2nd week) on the linked ears montage using the Neuroguide software program and sLORETA.Results: Thirty-two participants were enrolled and 2 participants dropped out because of personal reasons. Among the 30 participants, EEGs of 12 participants were included in the analysis of QEEG and sLORETA. Total score on the ISI and PSQI was significantly decreased after acupuncture treatment. The number of electrodes exceeding the range of 90% (±1.65) or 95% (±1.96) in the z scored absolute power of beta was significantly decreased after acupuncture treatment. There was no significant change in brain activation between pre- and post-acupuncture using sLORETA.Conclusions: The deviation of absolute power compared to the normative database was significantly decreased after acupuncture treatment in the alpha and beta ranges. Therefore, we suggest that acupuncture treatment for insomnia might be effective through the central nervous system especially in the brain. There are many limitations to drawing any conclusion. Further studies are needed in the future to overcome these limitations.

The aim of this study was to investigate the effect of hip external rotation angle on pelvis and lower limb muscle activity during prone hip extension. Sixteen healthy men were recruited for this study. Each subject performed an abdominal drawing-in maneuver (ADIM) in a prone position, and extended the dominant hip at three different hip external rotation angles ($0^{\circ}$, $20^{\circ}$, $40^{\circ}$) with a $30^{\circ}$ hip joint abduction. Activity of the gluteus maximus (G Max), gluteus medius (G Med), and hamstring (HAM) and the G Max/HAM and G Med/HAM ratios were determined with surface electromyography (EMG). The EMG signal was normalized to 100% maximum voluntary isometric contractions (MVICs) and expressed as %MVIC. Data were analyzed by one-way repeated analysis of variance (alpha level=.05) and the Bonferroni post hoc test. Significant differences in G Max and G Med muscle activity were noted among the three different hip external rotation angles. G Max muscle activity increased significantly at both $40^{\circ}$ (p=.006) and $20^{\circ}$ (p=.010) compared to a $0^{\circ}$ hip external rotation angle. G Med muscle activity increased significantly at $20^{\circ}$ (p=.013) compared to a $40^{\circ}$ hip external rotation angle. The G Max/HAM activity ratio increased significantly at both $40^{\circ}$ (p=.004) and $20^{\circ}$ (p=.014) compared to a $0^{\circ}$ hip external rotation angle. The G Med/HAM activity ratio increased significantly at $20^{\circ}$ (p=.013) compared to a $40^{\circ}$ hip external rotation angle. In conclusion, $40^{\circ}$ and $20^{\circ}$ hip external rotation angles are recommended to increase G Max activity, and $20^{\circ}$ hip external rotation is advocated to enhance G Med muscle activity during prone hip extension with ADIM and $30^{\circ}$ hip abduction in healthy subjects.

This paper intends to examine the significance of the "Minjoong Misool(People's art)" of the 1980s emerged in Korea in its social, cultural, and art historical context. This paper also aims to provide an analysis of the meaning and form of the individual artist's works, which have been overlooked under the dominant discourse that has emphasized their political role as a collective group. In particular, this paper scrutinizes the work of "Critical Realists" by examining the way in which they perceived Korean society in the early 1980s and visualized their experiences of the period. The figurative art newly emerged in the early 1980s challenged the formalist Modernism, which was adopted into Korea and translated into monochrome paintings and the work of the conversative academicism of the 1970s. The figurative art encouraged a social communication and moreover it intended to criticize the conflicts in the political, economical, and social domains in Korea. The targets of its critique include the unavoidable results of the unprecedented development of economy, various social phenomena of the post-industrial society, and the growth of the commercialized kitsch culture. Along with Shin, Hak-chul's work that incorporates collage technique since the 1980s, the work of some members of "Reality and Utterance" and "Im- sul-nyun" exemplify their critical interests in disclosing the false dream of wealth and happiness by both referring to and drawing on the utopian fantasy manipulated and distributed by mass media and commercial advertisements. This paper pays particular attention to Nouvelle Figuration emerged in France and Europe during the 1960s, which is comparable to the new figurative art emerged in Korea during the 1980s. Nouvelle Figuration criticized the autonomy in art isolated itself from political and social reality after WWII, in particular the indifference of Informel and abstract art as well as American abstract art. Moreover it became rather politicized around May of 1968. Given that French Nouvelle Figuration was introduced in Korea in 1982 and made a significant contribution to the formation of figurative art in Korea, it should be noted that the new figurative art emerged in the 1980s in Korea cannot be categorized merely in relation to People's Art. This paper intends to critically redress the notion that People's art was formed in the particular political, economical, and cultural context of Korea independent of the contemporary artistic practices outside Korea. It will provide a critical examination and analysis of the content and form of the new figurative art, from which People's Art was germinated, in the global context.

Effect of the egg yolks from laying hens intubated, p.o., astaxanthin (designated AEY) on mouse humoral immunity was investigated using male ICR mouse (6~7 weeks of age). Mice were adapted in a temperature- and humidity- controlled house for one week and randomly divided into 5 treatment groups (9 mice/cage/treatment). Mice were intubated p.o., AEY (100, 250 and 500$\mu\textrm{g}$) or control egg yolks (CEY, 250$\mu\textrm{g}$), dissolved in 0.1 mL DMSO, for consecutive 4 days. At day 5, carbon suspension (pilot drawing ink 3 mL+3% gelatine 3 mL) was injected 3 $\mu$L Per 1 g body weight through tail vein. Carbon clearance time was measured at 5 and 35 minutes Post the injection of carbon suspension. Another two experiments were conducted to determine the hemagglultinin-titer (HGT) and hemolysin-titer (HLT) with male ICR mouse (8 mice/cage/treatment). Mice treated with AEY were induced immune activity with SRBC. HGT and HLT were measured from the blood at day 1 and 3 after treatment of SRBC. AEY treatment reduced the carbon clearance time. Especially the carbon clearance time by 500 $\mu\textrm{g}$ AEY treatment was 5.00 minutes, which was very short time compared with 9.42 minutes by control and 9.01 minutes by CEY. AEY group showed slights higher values of HGT and HLT than CEY group and control. At day 1, HGT in control, 250$\mu\textrm{g}$ CEY and 250$\mu\textrm{g}$ AEY groups was 5.50, 5.63, and 6.00, respectively. Similiarly, HLT in control, 250$\mu\textrm{g}$ CEY and 250$\mu\textrm{g}$ AEY groups was 4.75, 5.38, and 5.50, respectively, at day 1. These results suggest that AEY exhibited immunity-enhancing effect.

South Korea has long been a culturally homogenous society, yet the increasing number of immigrants has turned the country into a multicultural society. Therefore, many empirical studies have investigated the way immigrants adapt to the Korean society and its associated factors. However, examining the overall process of migration (from family separation to reunification and cultural adaptation to the host society) that immigrant youth usually experience has been understudied. Previous empirical research and theoretical work have identified prominent factors that predict immigrant youth's mental health: experiences of family separation, living with others rather than primary caretakers during the separation, the length of residency in the host society, and family and peer support. In this respect, this exploratory and preliminary study that examined whether the experience of migration process and post-migration are related to Korean immigrant youth's mental health problems (depression, anxiety, and suicidal ideation). The result indicated that longer duration of family separation; living with relatives, siblings; and friends rather than primary caretakers during the separation; receiving less support from family and peer after migration; and a lower degree of cultural adaptation to Korean culture were associated with depression, anxiety, and suicidal ideation. Drawing upon the results, this study discussed implications for policy and practice.

The purpose of this study was to explore the learning effects in elementary school students who participated in a geological field trip conducted under the theme 'minerals and rocks', focusing on novelty space. A total of 10 sixth-grade students participated in this program held at a public elementary school in Seoul as part of after-school club activities. Students observed mineral and rock samples in a classroom and outdoor learning environment. The authors collected activity papers (texts, drawing), researchers' participation notes, video and audio recordings containing the study participants' activities, and post-interview data To analyze the learning effects in the cognitive domain of students, the observation analysis framework for rock classification of Remmen and Frøyland (2020) and the rock description analysis framework of Oh (2020) were used. Additionally, to explore the learning effects of psychological and geographic areas, students' drawings, texts, discourses, and interview data were inductively analyzed. The results showed that the students demonstrated 'everyday' and 'transitional' observations in the classroom learning environment, while in the outdoor learning environment (school playground, community-based activities), they demonstrated 'transitional' and 'scientific' observations. Moreover, as the scientific observation stage progressed, more types of descriptive words for rocks were used. In terms of psychological and geographic aspects, students showed their selection of places to explore familiar outdoor learning environments, positive perceptions of outdoor learning, and aesthetic appreciation. Finally, this study not only discussed novelty space as a tool for analyzing students' learning effects but also suggested the need for an academic approach considering new learning environments, such as learning through virtual field trips.
